This Quick Release Plate for TB-200 Tripod from Magnus is a replacement or spare for those who want to use the quick release for more than one camera. The featherweight (0.3 oz) plate is fabricated from ABS plastic and topped with a rubberized non-slip surface. The standard 1/4"-20 tripod screw mounts quickly to your camera via a fold-away tightening key on the underside of the plate.
